7 Claims. 1

This invention relates to punching machines and more particularly to thetype which effects punching of a record inserted in the punchingmechanism to represent an amount which is in accordance with an amountpreviously set up by a keyboard.

Heretofore, when such records were of the same dimensions no particularproblem arose in presenting such records to a punching mechanism so thatthe location of punched holes will be at predetermined points in orderthat they will be registered with the sensing mechanisms of anothermachine that such punched records are to control.

However, when it is desired to punch records having variable sizes, suchas checks which now come in diiizerent widths and lengths, the locationof the holes must be at the same places for all records or checks inorder to be properly registered with the sensing mechanism.

An object of the present invention is to provide means to insure theproper displacement of a check in the punching mechanism in bothdirections prior to feeding the check into the punching mechanism.

A further object of the present invention is to provide means to insurethat when a check or record is inserted in the punching mechanism itsbottom edge will be at the proper position before punching can beefiectuated.

A still further object of the invention is to provide means toautomaticall cause the lateral displacement of the inserted record orcheck preferably aiter its bottom edge is properly located to the exactposition necessary for punching holes in the required places.

A further object of the invention is the provision of electrical contactmeans which cooperate with the bottom edge of the record to insure itsexact position with regard to the punching mechanism and which contactmeans must be closed before the further operation of the machine can becarried out.

A still further object of the invention is the provision of electricalcontact means which are actuated when the lateral displacement of therecord is completed to initiate the further operation of the machine.

The present improvements are preferably incorporated in a form ofcombined sorting and accounting machine shown in the U. S. Patent to F.L. Fuller and S. Brand, No. 2,142,352, to enable records to be punchedaccording to amounts set up in a ten-key keyboard of the accountingmachine prior to their sorting in a plurality of compartments. Whilethis has been attained in the patent to S. Brand No. 2,161,612, thepunching arrangement therein was only adapted to punch statistical cardsof equal sizes which were to be utilized in card controlled accountingmachines. This punching arrangement was not adapted to handle and punchpaper checks of various widths and lengths. It is, therefore, anadditional object of the present invention to devise a check punchingarrangement which can receive and punch paper checks of variable sizesand with provisions of means to handle and centralize the checks in apunching mechanism irrespective of their sizes, so that punched holescan be made at predetermined points in order that they will beregistered with the sensing mechanisms of another machine that suchpunched checks are to control.

A still further object of the present invention is the provision of anelectrical setup or digit representing mechanism set up under control ofa ten-key keyboard from which amounts may be derived or read out tocontrol desired recording mechanisms, such as the punching mechanismherein.

It has also been contemplated in French Patent, No. 968,468 to providefor punching of checks of various sizes at exact places by the use of apilot hole on the check which determines the lateral displacement of thecheck. The present arrangement not only eliminates the requirement ofsuch pilot holes but the sensing mechanism therefor, and also thecontrol by the latter of the check feeding mechanism.

Other objects of the invention will be pointed out in the followingdescription and claims and illustrated in the accompanying drawings,which disclose, by way of example, the principle of the invention andthe best mode, which has been contemplated, of applying that principle.

General description of basic machine The present improvements arepreferably in-- corporated in the form of combined sorting andaccounting machine shown in the U. S. patents issuedto F. L. Fuller andS. Brand, No. 2,142,352, dated January 3, 1939, and No. 2,146,695,issued to S. Brand and J. N. Wheeler, dated February 7, 1939.

The combined sorting and accounting machine is shown in a general mannerin Fig. 1 with the improved check printing and punching unit P mountedthereon. Without the latter unit it represents the form of machine whichis now used commercially in banks to sort a group of promiscuouslyarranged checks. The operator is provided with a group of checks whichhave different classification symbals and in accordance with theclassification symbol of a check one of the compartment selector keys20' on thekeyboard is depressed to select an appropriate check receivingcompartment 2| carried by a. sorting drum 22. Upon the depression of adesired compartment selector key 20 the sorting drum is rotated ineither of two directions to select a desired sorting compartment 2| bytheshorter of two directions of rotation. By means of the compartmentselector keys 20the extentzof rotation and the direction of rotation ofdrum 22. are predetermined and said keys control an'electromagneticallycontrolled stop mechanism of a well known form which cooperates withthesorting drum 22 to stop the drumat the desiredposition. All of themeans for carrying out the above function are well known and'fullydescribed in the above cited patents. The general description givenherein is to. make it clear that checks printed and punchedby theadditional unit forming the present invention-may, also be disposed 4 insorting compartments preselected by the compartment keys 20.

The function of the machine shown in the aforementioned patents hereinis to also effect the entries of the amounts on the checks selectivelyin a plurality of totalizers and to cause the listing of amounts on thecheck upon a main control tape and also upon separate compartment tapeswhich are associated with the plurality of sorting compartments. Toprovide for the entry and listing of the amountsthe machine is providedwith ten keys of a keyboard which are initially depressed so as tocontrol the setting on a suitable setup mechanism an amount equal in.value to therkeys struck. In the present machine such ten keys 6!! (Fig.3) of the keyboard control the differential setting of printing elementsand. punch selecting elements so that the amount may be both printed andpunched upon a check inserted inthe chute prior to feeding the check inthe preselected compartment. After the amount has beenset up on thesetup mechanism the operator then inserts the check in the checkreceiving aperture 23 and instead of depressing a motor release bar 24(Fig. 3) to cycle the machine the check itself? initiates the cyclicoperation. A number of functions are then performed among which isv thefeeding of the printed and. punched check by feeding rollers 25. intothe selected compartment and also thepositioning of the totalizeractuators and printing mechanisms in order that: the amounts may beentered in a grand totalizer and selectively into one of a plurality ofcompartment totalizers, and furthermore one of a plurality ofcompartment printingmechanisms associated with the compartments will beselected for operation so..as to print the amount on the selectedcompartment tape. A printing mechanism is concomitantly adjusted so asto print the same amount on the control tape.

Ten-key controlled amount setup mechanism The ten-key keyboard mechanismis provided for setting up amounts read by the operator and for causingthe amount to be punched and printed on checks before they are sorted.Any suitable ten-key keyboard mechanism may be used and one type thatmay be used is fully shown in the application of F. J. Furman et al.,Serial No. 217,118, filed March 23, 1951, and only that much of itsconstruction and operation that is necessary to understand the presentinvention willbe explained.

During the rotation of the sorting drum to select a compartment inaccordance with the compartment selecting designation on the check andprior to the cycling of the machine the amount read on the check is setup by the tenkey keyboard. The purpose of the associated setup mechanismis to cause the punching and printing mechanism to be set in the unit P,after which the cyclic operation of the machine is initiated by theinserted check after it has been punched and printed.

The. ten-key keyboard unit has ten numeral keys'ell (Fig. 4) which arearranged in a conventional ten-key keyboard arrangement and upon theupper protruding ends of the slidable key stems 6| there are mounted thekey. caps which designate the digital. value of each key. The key stemsslide in a slotted guide plate 62 andat their lower ends they are eacharticulated by a pin 63 to a hook operating arm 54, all ten of. whichare pivoted on a rod 65; each arm fi l being urged by an associatedspring 66. against a stop bar 61, said spring 66 also normallyfunctioning to return each key after it has been depressed, as well asto return the associated arm 64 against the stop bar 61. Each arm 64carries a stud 68 projecting against a finger 69 of an associated arm Ihaving a hooked end I I. Each arm I0 is pivotally mounted by a stud. I2to the associated stop pin raising arm I3. Each arm I3 is urged by aspring I4 to normal position, shown in Fig. 4 and all of said arms I3,of which there are ten, one for each key 60, are pivoted on a rod 18. Itwill also be seen that a spring I9 connected between a hole in the pinraising arm I3 and related arm I0 retains the finger extension 69against the stud 68, as is shown in Fig. 4.

So far it is evident that when a key 60 is depressed by the finger ofthe operator it will rock hook operating arm 64 counterclockwise againstthe action of the spring 66, causing stud 68 to act against the finger69 to rock the arm slightly counterclockwise to bring the hook end IIunderneath a power-operated bail as. It is evident, therefore, that theonly load upon the operator in depressing a key is that required to rockthe arm I0 so as to place the hook-shaped and II beneath the bail 80,the power required to do so being very slight due to the weak springs I9and 65. After the hook-shaped end II is caught underneath the bail 80there is a power operation of the bail 80 by electrical power meansinitiated in operation by the following described mechanism. Bail 80 issecured to a rock shaft SI and secured to said shaft 8i there is an arm82 which is articulated by a stud 83 to the core 84 of a power solenoidS5. The bail 80 is normally held in the position shown in Fig. 4 bymeans of a spring 86 connected to said arm 82.

Extending beneath each of the key stems SI, which are of such shape thatthey are in a single line at their lower extremities, is a bail 96 whichis pivoted upon a rod 9|. One arm of said bail 90 is connected by a stud92 to a contact operating member 93 which is urged by a spring 95 sothat its left-hand extension fits in slots 95 of the blades of contacts96. The spring 94 also retains contact operating member 9-3 so that itsshoulder 91 is immediately adjacent the lefthand contact blade.

When said bail 90 is rocked counterclockwise it will, through its pivotstud 92 move contact operating member 93 slightly to the right, asviewed in Fig. 4 so that shoulder 9'! bearing against said left-handcontact blade will close contacts 96. It should be noted that closure ofcontacts 96 is timed to take place after the hookshaped end II of thearm I0 associated with the depressed key is beneath the bail 80 and'alsothat the additional load placed upon the finger of the operator to closesuch contacts 96 is not great because of the weak spring 94 and theslight power required to close the contacts 98.

Thereafter, a circuit is completed from the positive line side (Fig.through solenoid 85, contacts 96, to the negative line side to energizesaid solenoid 85 which thereupon attracts its core 84 (Fig. 4), rockingthe bail 80 clockwise and through the hooked arm I0 connecting it withthe bail 80 rocking the associated pin setup or raising arm I3counterclockwise against the action of spring 7-0 to set up, in a mannerto be described, a pin in a pin setup carriage representing the digit ofthe key depressed. This operation takes place without effecting anyfurther movement of the key since, at this time, the

finger extension 69 will merely ride down against the stud 68 withouteffecting any movement of the rocked arm 64 or the interconnected keystem 6|.

Near the end of the solenoid plunger power stroke a stud I05 on an armof the bail 80 operates against the upper edge of the contact closingmember 93, rocking the latter slightly counterclockwise and disengagingshoulder 9'1 from the left-hand contact blade of contacts 9t so that bytheir inherent resiliency said contacts 96 again open and deenergize thesolenoid 85. The depressed key must be returned to nearly its normalposition before spring 94 will rock member 93 so as to re-engage thecontacts 96 for another closure thereof. Also the hooked arm I6 is notdisengaged from the bail 80 until near the end of the return stroke ofthe solenoid core 80. Therefore, the depressed key must be returnednearly home before another key can be depressed, or a redepression ofthe same key can be effected. At this point the rocked arm 64 isreleased from the well known single key interlocking mechanism so thatanother key can be depressed,

In the differential mechanism the setup pins or stops H0 are arranged ina transverse series as shown in Fig. 4 in which all pins in eachtransverse series represent the same digit and in which the pins orsteps are also arranged in longitudinal series (Fig. 5) in numericalorder 08 and all the pins are capable of being selectively set to limitthe movements of actuating devices.

The pin setup carriage which is designated generally by the referencecharacter III (Fig. 5) includes a U-shaped plate II2 carrying rollersII3 which are slidably mounted in tracks II I (Fig. 4) each formed by ashoulder in castings 5 (Fig. 5) and a cap plate I I6 secured thereto. Bythis means the pin setup carriage is moved step by step as thelongitudinal series of stop pins IIO are successively set up torepresent the digits of the keys depressed. The carriage is urged to theleft as shown in Fig. 4 by means of a spring II1 connected to thecarriage, the step-by-step movement being under control of an escapementmechanism to be subsequently described. The several series oflongitudinal stop pins N0, of which there are nine longitudinal seriesfor setting up a number having nine denominational orders, are slidablymounted in a bottom guide plate I20 and upper guide plates I2 I, both ofsaid guide plates I20 and I2I being carried by and mounted within theU-shaped plate II2. As best shown in Figs. 4 and 5 the pin raisinglevers I3 for keys 0-8 have nine fingers or extensions II 8 whichproject through said pin setup carriage as shown in Fig. 4 so as toraise an associated stop pin IIO corresponding to the digit key 0-8depressed of the effective longitudinal series. For each longitudinalseries of pins IIO there is a springurged detent plate I22 carrying pinsI23 which engage one or the other of a pair of notches in each stop pinIIO to hold the pins IIO down in normal position, or one in elevatedposition, as is well known in such detent mechanism.

Secured to the U-shaped frame plate H2 and carried thereby in anysuitable manner are two upstanding side plates I25 and I26 (Fig. 4). Toside plates I25 and I25 are attached the guide plates I20 and I2I, asseen in Fig. 4. Thus, an extension of the pin carriage is provided andthe upper portion of said carriage has cross connecting members, such asguide bars I21 and 7. I28 (Fig. 5) on which certain members are slidablymounted, as well as supporting shafts I26 and I30 and cross bars I3I andI32. These cross members provide a rigid frame which is an extension andpart of the movable pin carriage.

Pivotally mounted on a rod I35 also carried by side frame members I25,I26 is a series of spring-urged latch members I36, each having a hooknormally engaging a shoulder I3I of a series of setup slides I38slidably mounted in the pin setup carriage by the guide rods I21 andI28. A spring I39 attached to each rack I38 urges the latter to theright to cause the hook of the latch member I36 to normally engage theshoulder I3I of the associated slide I38. Each latch member I36 has anextension I40 adapted as the step of movement of the pin carriage movesthe effective longitudinal series of stop pins out of engagement withthe extensions II8 after a stop pin in said series has been set up, toengage the cam edge I4I of a stationary cam plate I42 (see also Fig. 3).

As is viewed in Fig. 3, if the first or left-hand longitudinal series ofpins has been set up to represent the digit of the depressed key a stepof movement of the pin carriage will cause the extension I40 of thelatch I36 of the associated series to engage the cam edge I4I which camedge will cause the rocking of the latch member I36 clockwise (Fig. 5)to disengage it from the setup slide I38. The spring I39 attached tosaid slide I38 will now move it to the right until a depending extensionI43 thereof strikes the elevated pin stop IIO. It is, of course,understood that the release of the slide I38 occurs after the pin IIO'has been raised and held elevated by the detent plate I22. Each slideI38 has rack teeth which mesh with a gear I44 having on the peripherynumeral indicia which are visible through a slot in the cabinet so thatthe numerical value of the previously pressed key is exhibited. As thecarriage moves step by step the indicia are brought into view, torepresent a number which has been set up.

The escapement mechanism is provided for obtaining the step-by-stepmovement of the pin carriage to the left, as viewed in Fig. 3, as theseveral longitudinal series of pins IIO are set up by the successivedepression of the keys. Underlying the ten pin raising arms I3 for keys-9 is a bail I50 secured to the rock shaft I8, said bail I 50 having, asshown in Figs. 3 and 4, depending arms II and I52, said arm I52 havingconnected thereto a spring I53 which is adapted to return the bail tonormal position after having been rocked by the arms I3. I52 moves backand forth between a pair of adjustable stops I54 (Fig. 3) which limitthe exthe stud I51 and rocked by. a spring similar to.

spring I59 so that its tail I63 overlies a. lug, I64 offset from theescapement operating arm I55. An escapement rack I65. is carried by theside plates I25v and I26, said rack having es capement teeth I66 and theescapement rack.

I65 is. of. sufiicient thickness so that the: teeth Arm 8 I66 cooperatewith both the locking dog I62 and the escapement dog I58.

When the pin setup carriage is at its normal position having previouslybeen returned to such position, the locking dog I62 engages the extremeleft-hand tooth of the escapement rack I65, as shown in Fig. 3, to holdthe pin carriage at normal. When bail I56 is rocked downwardly throughthe first power operation of the selected pin raising arm I3 shaft I8will be rocked counterclockwise and rock the escapement operating armI55 in the same direction and by the offset lug I64 in cooperation withthe tail extension I63 of the locking dog I62 the latter will be rockedclockwise against the action of its spring. In the meantime, however,spring I58 causes the stud I60 to follow the finger IGI, allowingescapement dog I58 to be rocked upwardly as the locking dog I62 movesout of engagement with said first tooth, the pin carriage is now movedby its spring III (Fig. 4) a slight amount but not a full step ofmovement. When bail I50 is returned by its spring I53 escapementoperating arm I55 will now be rocked clockwise and finger I 6-I actingon pin I60 will rock escapement dog I58 out of engagement with saidfirst tooth. In the meantime, however, locking dog I62, being rockedupwardly to cause an ultimate engagement with the second tooth and whenthe escapement dog I58 fully clears said first tooth the spring I llwhich moves the pin setup carriage will move it the remainder of thedistance determined by engagement of locking dog I62 with the secondtooth to thereby complete the first step of movement of the pincarriage. This form of an escapement mechanism is well known and itsoperation is only generally described herein, it being noted, however,that the escapement operation is not performed by the power applied tothe keys but is operated by power derived from the solenoid which, itwill be recalled, is the instrumentality for rocking the selected pinraising arms I3. and bail I53. Hence, the manual power required bythekeys'in the previous pin carriage setup mechanisms for operating theescapement isavoided, and by causing the power operation of theescapement mechanism the load upon the fingers of the operator is.

further lessened, which aids in a lightened key load and faster keyoperations.

It is also explainedthat the 9 key does not cause the setting up of anyof the stop pins I I0 because there is no pin raising extension IIS forthe 9 key and no stop pin H3. Only the digit keys 0-8 inclusive raise0-3 stop pins H0. The arm I3 related to the 9 key, however, doesoperate- 0-8 setup slides. I38 take a commensurate move ment. As thecarriage moves step by step the setup slides I38 are alsomoved step bystep.

It will be observed that whenever a 9 key is operated, although no stoppin H0 is set up, the latch. member I36 associated with the longitudinalseries of pins II.0now effective is, nevertheless, rocked to unlatch theassociated setup slide I38 which will be moved to a 9 position by itsspring I35 until its extension I43 strikes a rod I15. This'rod isstationary during the operation of the keys.

After the setupslides I38- have received their differential movementsand the latched pins IIO have functioned as stops for setup slides I38,said pins IIO are depressed to normal position by the aforementioned rodI15. The pin carriage is restored at the same time as will be describedlater.

The rod I15 passes through side frames I25 and I26 (see Fig. 4) andcarries rollers at its extremities which roll in guide slots formed incastings I16. The rod IE5 is connected by a pair of links I11 and I18(Figs. 4 and 6) to respective rock arms I80 and I19, both being pivotedon a rod I8I (Fig. 4). The arm I19 (Fig. 6) is, as is fully described inthe aforementioned application, rocked by a cam connected to the maindrive shaft of the machine. When said shaft is turned one revolutionduring the cyclic operation of the machine, the cam will, through thelinkage just described and during the last portion of the cycle, causerod I15 to be moved to the left to engage the upper bevel portions ofthe raised pins IIIJ, thus depressing them to normal position and alsoengaging the shoulders I43 of each of the unlatched setup slides I38 sothat the latter are moved back by the rod I15 to normal position wherethey are relatched by the latch members For returning the pin setupcarriage to home position where it is held in such position by theescapement mechanism, one arm I88 carries a stud I90 (Figs. 4 and 6)which engages an upward extension I9I of a bell crank I92 pivoted on astud I93. The arm I 94 (Fig. 6) of said bell crank engages a pin I95carried by the U-shaped plate H2 and as the bell crank is rocked the pincarriage will be returned to normal at the end of the cycle and held atsuch normal position as shown in 3 by the locking dog I62, it beingnoted that during such return locking dog I 52 merel ratchets over theteeth of the escapement rack I65. During the return of the carriage thecarriage return spring I I1 (Fig. 4) will also be retensioned as isevident.

Difierentially operated operating mechanism in basic machine controlledby the ten-key setup mechanism for eflecting entries in accumulators,setting printing mechanisms, etc. The basic machine includes and thepresent machine may also include a differential mechanism which iscontrolled by the ten-key keyboard for effecting entries in a selectedtotalizer, set up different printing mechanisms, etc. This mechanism isfully shown and described in the aforementioned patent to F. L. Fullerand S. Brand. No. 2,142,352, but in order to have a generalunderstanding how this is eifected it explained that as the setup slidesI38 .are released for differentially positioning to the right. and. alsoare moved laterally step by step to the left the square studs I10carried by said slides I33 come into the plane of the hooks I'll ofcontrol slides I12. After the desired digits have been set up, one ormore setup slides 538 will be positioned at the left by the carriage forsecuring this relationship and the square studs I10 will be atdifferential distances to the right from the hooks Ill of the slidesthey are to control. The hooks I1I are normally above the studs I and asis well known such slides I12 are moved downwardly at their hookportions so as to be stopped by the related stud I10 when each slide5172 is moved to the right during the cyclic operation of the machine.The control slides l'l2.thus move to the right until they are arrestedby the studs I10 and the differential positions of the slides I12 areutilized to control the difierential movement of totalizer actuators,and the printing elements 10 of the main control tape and thecompartment printers. At the end of the cyclic operation of the machinethe slides I12 are restored and elevated to the position shown in Fig.5.

Keyboard controlled electrical digit readout R01 on the check.

The electrical readout unit R0 (Figs. 5 and 6) consists of a supportplate 98 of insulating material having embedded therein for each ofthenine columns a column contact strip 99 and the ten digital contactpoints I (see also Fig. 15). There is a digital contact point Illil foreach of the digits 0-9. Each setup slide I38, as best shown in Figs. 5and 6, carries an insulated plate IiII having the integral column stripcontact finger I04 and digit contact finger I (see Fig. 15). Obviously,according to the digital position 0-9 of each setup slide I38 theassociated plate I Ill will be in such position that finger I06 willmake contact with one of the 0-9 digital contact points I00 and itsother finger I84 will be in position to make contact with the columnstrip 5'9. If a setup slide I38 is not moved plate It! is not moved andits fingers I94 and I06 will remain in contact with the insulation ofplate 98. Since setup slides I 38 and plates I8! with the contactfingers IIM and I 86 carried thereby move step by step to the left asthe successive key strokes are made, each key stroke increases thenumber of columns representing some digital value 0-9. In amountentering operations all unkeyed columns remain at blank positions sothat nothing is punched or printed for these unkeyed columns.

The support plate 98 and contact strips 99 and contact points I00carried thereby are normally positioned above the contact fingers I84and llt, as shown in Fig. 5, in order that the setup slides I38 may befreely moved to differential positions and laterally step by stepwithout adding resistance thereto which would happen if the contactfingers IM and I06 directly wiped under the contact elements as and I08. To this end the contact plate 98 is supported at the right side(Fig. 6) by bell cranks I01 which are pivoted on studs I08 carried by anupstanding frame plate I09. Said bell cranks I01 also have holesreceiving pins I 45 carried by brackets attached to the right side ofthe support plate 98. The vertical arms of the bell cranks I81 areinterconnected by links I46 to hell cranks I47. Thus, the left side ofthe plate is supported by similar supporting means, as shown in Fig. 6,the associated bell cranks Ml having pivotal connections to the leftside of plate 938. One bell crank M1 thereof has an extension I 38 towhich alink I 49 is, secured, said link being connected to an extensionof an armature I82 of a magnet 183. Said magnet I83 when energized in amannor to be explained rocks the armature I82 and through link I49 rocksthe four bell cranks I41 and I8! supporting the plate 98 to lower saidplate 98 enabling contact fingers I04 and H36 to make contact with thecolumn strip 99 and digital points me. As will be presently described inconnection with the wiring diagram an impulse is transmitted at theproper time to this 11 magnet sothat the settings of R may be used as acontrol for the punching and printing mechanism. When the magnet isdeenergizedthe plate 93 is returned to normal by a suitable spring I8 4.

Operation of aligning contact means So far it has been stated that afterthe desired compartment has been selected by the compartment selectorkeys 20 and the amount which has been read thereon is set up in theten-key mechanism by the operation of keys 60 corresponding to theamount on the check, the operator then inserts the check intothe unit Pnow to be described so as to cause the automatic perforating of thecheck and printing of the amount thereon and then the feeding of saidcheck to the selected sorting compartment. The operator places the checkin a slot 23 (Figs. 1 and 13) between guide plates 200 and 20I (Fig. 12)until the lower edges abut ledges 202 (Fig. formed on a respective arm203 pivoted on a roller drive shaft 204. Preceding engagement with theedge 202 the lower edge of the check actuates a contact operating member205 pivoted at 206 on the respective arm 203 and urged by a spring 20'!to the position shown in Fig. 10. The contact operating lever 205 ismade of an insulating material such as plastic and spring 201 is a lightspring so as to enable the easy rocking of the contact operating lever205 so as to project a wire 208 against a contact terminal 200 so as toclose contacts 208-200 (see Fig. 14). The arrangement shown in Fig. 10is quadruplicated and connected in a series parallel, as shown in Fig.so that the bottom edge of the inserted check at the left and right endsmay close one pair of such contacts 208-400 in shunt. Any two pairs ofcontacts in series complete a circuit to a lateral feed magnet 2I0 whencam contacts CB3 close. The contacts are closed by a the right and leftends only when the inserted check is properly inserted in the chute atwhich time the bottom edge abuts the ledges 202 of the arms 203.

Lateral check feed The lateral check feed rollers are best shown inFigs. 7 and 8 and comprise four pairs 2I2, 2I3 which are normallyseparated to allow the free insertion of a check in chute 23. Therollers 2 I3 are constantly driven by the following driving mechanism.Referring to Fig. 9, a motor 2" is the prime mover of the 'Punit nowbeing described and the armature shaft thereof drives a speed reductionmechanism 2I5. The reduced drive shaft 2 I9 has secured thereto a pulley220. The latter through a belt 22I rotates a pulley on shaft 222. Thelatter carries a gear 223 in mesh with a gear 224 secured to atransverse drive shaft 225. The latter carries worm wheels 226, each ofwhich meshes with a respective gear 221 secured to a respective stubshaft to which the related roller 2 I3 is secured. A fixed supportingbar 228 carries the rollers 2I3, related stub shaft, and worm gear 221.In this manner the feed rollers 2 I 3 constantly rotate in a directionwhich would feed the check to the right when the pairs of rollers 2I2and H3 are in cooperation with each other. Each of the rollers 2 I2 iscarried by a bell crank 230 pivoted at 23I to a bar 232. Each bell crank230 is urged by a spring 233 connected to a stud 234 of the associatedbell crank 230 and a stud 235 carried by a link 236 so as to normallyattempt to cont-act its associated roller 2I3 but is prevented from sodoing by the contact of stud 234 with. the termination of a slot 231 inthe link 236. However, when said link 235 is moved to the left by meansnow to be described it will enable spring 233 to rock the related bellcrank 230 so as to cause feed roll 2 I2 to contact with the associatedroller 2I3. Contact of the four pairs of rollers to thus frictionallyengage the check inserted therebetween is effected by moving link 236 tothe left by means now to be described.

Referring to Fig. 13 the armature 200 of the lateral check feedingmagnet 2 I 0 normally latches a double follower arm MI by engaging ashoulder 242 on an extension thereof. The upper arm 24I has a linkconnection 244 which is articulated to a bell crank 2 45 (Fig. 8)pivoted on a fixed stud 245 and which has a pivot connection 248 to theaforesaid link 236. When said follower arm 2M is unlatched it is rockedby a spring 250 (Fig. 13) so that through link 2 and bell crank 245 thelink 236 is moved to the left, allowing each of the springs 233 to rockthe respective bell cranks 230 and rollers 2l2 into engagement with theconstantly rotating feed rollers 2 I 3. This will feed the check to theright until its right edge makes contact with an insulating contactblock 25I (Fig. 8) to close contacts 252. The check comes to the rightendwise by an abutment 253 (Fig. 8), the sets of feeding rollers 2I3,2I2 frictionally urging and retaining the check in such position. Afterthe printing and punching operation a high portion 260a of a cam 260secured to a drive shaft 26I engages the follower roller of double arm2M, thereby separating the sets of feeding rollers 2 I3 and 2 I2 afterenabling the armature 200 of magnet 2I0 to relatch the double arm 24I tothus retain the sets of rollers separated. In the open position of thefeeding rollers 2I3 and 2I2 the punched check is fed downwardly by meansto be subsequently described into the selected sorting compartment.

Main drive clutch of P unit Referring now to Fig. 15, it will be seenthat when all pairs of contacts 208209 are closed a circuit is completedthrough such contacts, start contacts 252, cam contacts CBI now closed,and a clutch magnet 265. A circuit is also completed through RI relay,magnet I83, CB2 contacts. Even if contacts 252 open, magnet I83 is heldenergized by CB2 contacts, and RI relay con tacts, until CB2 open.Referring now to Fig. 9, it will be seen that the speed reduction shaft2I3 has afiixed thereto a gear 266 meshing with a ratchet wheel orclutch gear 261 and said clutch gear constantly rotates on a shaft 260.Loosely mounted on said shaft 263 is a gear 269 to which is affixed anarm 2T0 upon which is pivoted a clutch pawl 2' which is normally latchedin such position that it cannot engage the clutch gear 261 due to aclutch arm 212 which is part of the armature of clutch magnet 265. Theabove refers to a Well known form of one-revolution clutch which, uponenergization of clutch magnet 265 enables clutch pawl 2'I'I to engage atooth of the constantly rotating clutch gear 261 to thereby rotate saidarm 210 and the amxed gear 269 one revolution in a counterclockwisedirection. Gear 269 drives shaft 26I through a series of gears 213,thereby driving shaft 26I one revolution for each operation of the unit.Said shaft carries the aforementioned cam 260 (Fig. 13) as well as otheroperating cams which will
